Note: CBSA has clarified the apparent disconnect between Prime Minister Carney’s statements and the updates. The exemptions are not based on the ability to claim blanket CUSMA but instead are setup to protect certain business sectors while eliminating the barriers from others. This does not establish any across the board surtax tied to CUSMA exemption qualifications.
